TWINE CUTTER Filed June 20, 1929 15 0 L'rgfi Patented May 27, 1930 ARTHUR GUY GROFT,.OF BOISE, IDAHO- Y TWINE CUTTER Application filed June 20,

The invention aims to provide an exceptionally simple and inexpensive, yet an efficient and desirable device for use on store counters and the like for the purpose of cut- 6 ting twine used in bundle wrapping.

The device embodies a safety razor blade clamped against an arm by a clamping plate and fasteners which pass through said plate, said blade and said arm, and a further aim is to provide a novel guard for the blade carried rigidly by said plate and hencerequiring no attaching means other than the aforesaid fasteners.

A still further aim is to provide a unique construction in which a portion of the aforesaid guard and a shoulder on the abovenamed arm, are instrumental in elfecting alinement of the fastener-receiving openings.

With the foregoing in view, the invention resides in the novel subject matter herein.- after described and claimed, description being accomplished by reference to the accompanying drawing. i

' Fig. 1 is a perspective view of a twine cutter constructed in accordance with my invention.

Fig. 2 is a fragmentary disassembled perspeotive view showing the arm, the clamping plate and the guard. a

Fig. 3 is a vertical sectional view as indicated by line 3-3 of Fig. 1.

In the drawing above briefly described, the preferred form of construction has been illustrated and while such construction will be herein specifically explained, it is to be understood that within the scope of the invention as claimed, variations maybe made.

The numeral 5 denotes a heavy horizontal baseto whose rear portion a post 6 is rigidly joined, said base and post being preferably cast as a single unit from appropriate metal. The upper end of the post 6 is turned forwardly and shaped to provide a horizontal arm 7 having flat vertical inner and outer sides 89 respectively and a flat -vertical shoulder 10 at right angles to and disposed at the inner end of the side 8. A safety razor blade 11 lies against the flat side 8 of the arm 7 and is held against the same by a flat clamping plate 12. This plate is formed with fas- 1929. '1 Serial No. 372,452. I

tener-receiving openings 13 for alinement with similar openings 14 in the arm 9, so that clamping screws or other fasteners 15 may be passed through these openings and through the usual openings of the blade 11, for securing thelatter tightly in place with its edge exposed.

Rigidly joined to the'rear end of the clamping plate 12 and preferably integral thereitwh, is a guard arm 16 which projects forwardly over the blade 11, preventing anyone from accidentally striking this blade and beingcut. The rear end of the arm 16. is of yond the inner side of said clamping plate providing a downwardly facing shoulder 17 This shoulder is adapted to rest u on the up:

greater width than the thickness of the clamping plate 12 and it projects laterally beper edge of the arm 9 and both said shoulder and the shoulder 10 are instrumental in alin- 1 ing the fastener-receiving openings when assembling the device. By resting the shoulder 17 on any portion of the upper edge ofarm 9 and then sliding the plate 12 rearwardly until this plate strikes the shoulderlO, the rearmost of the openings 1314 will be in substantial alinement so that the rear fastener 15 may readily be passed through them, and this having been done, it is an easy matter to aline the front openings to receive the other" may be easily and conveniently used, and is of-such nature as to readily permit quick and easy change of blades whenever desired.

On account of the existing advantages for the details disclosed, they are preferably followed. However, as above stated, variations may be made within tion as claimed. Y

I claim A twine cutter comprising a post provided with a'forwardly projecting rigid arm, said arm having a flat vertical side anda vertical shoulder at an angle to said fiat side, a flat blade bearing against said fiat side of said arm and projecting upwardlyfrom the latter, a clamping plate disposed against the so 7 the scope of the inven- H first named arm to assist in alining saidropena r ings, said clamping plate abutting the firstmy signature side of said blade remote from said flat side of said arm, said arm, blade and plate having fastener-receiving openings, a guard arm integral with the rearend of said clamping plate and projecting forwardly over said.

blade, said guard arm having a downwardly facing shoulder at its rear end lying uponthe named shoulder to further aid in alining said openings, and fasteners receivable in. said openings when alined. g a i I have hereunto-aifixed In testimony where ARTHUR GUY" CROFT.
